Litige hnelt-riferibili in tlgrst ttttett intent mit uniting putt n'filgt time 'IOl ALL WHOM IITAMAY CONCERN: i sa Be it known that I; DAVID O. WOLF, 'of South English, in the county of Kcolfuk, and State OfIowa, have invented a certa-in near and useful Improvement in Spinning-Machines; and I do hereby declare that the followinlr is a-full, clear, and exact description oi' the construction and operation'of the same, reference being had to the accompanying draw-ings, and to the letters Aandlinar-ks thcreonwhich said drawings form part of this specification, and represent a spi:ming-machine with inyjimprovement as :i Apart thereof!- Figure 1 beinga side view of the machine, I

Figure 2 a bncl: end view 'of the same,

Figure 3 a front end View, and

Figures 4, 5, and 6,views of the machine which will hereafter'be explained.

c In each of these figures like parts are indicated bylike marks and letters. A

The rolls from which the yarn is'to be spun are fed tothe machine between the rollers a and b, over the table c, to andb'etween the rollers d ef, and thence forward tothe spindles g and spools L. Theserollers have suitable bearings in the standard i, bar j, andlby arms 7c in'the table c. Motion is given to'ithese feed-'rollers during a certain portion of the forward movements of the carriage Z, by a cord or band, vmpassing around the" pulleys n and o, a like cord passing` from around pulleyp to the pulley g. The pulley vgisvonthe end of the shaft of rollerf. v Rollers d and e'have pinions, that of 'c gearing' into that o f d, while that 'efe also gearsinto the-pinion of the roller-f.` The feed of these rollers occurs only while thecord mis clamped by the lever 1 and the forks, as is indicated by the red lines of lig. 1. 'Theclamping and liberating-of the cord m is brought about by thelever r, and fork s, levert, pin u, and platen.- Thus, when the carriage` is travelling towards the A front part of the machine, the lower end of the lever 1' comes against the pin u', which forces theupper endbf the lever against the cord, andcarries the .cord up into the fork; Lever t is a spring-lever, acting upon lever r, and-binding thatV lever against the cord. As the carriage'is' travelling from the frontjtothe 'rearof the machine, the Aend'of the lever t comes against the outer edge of the plate o, which edge is elliptical, and by this plate the lever'tis forced outward, and the lever r, by this movement being `releas`d, drops and ceases its binding on the corclm. The plate-o is attached to the bar w by a screw, and may readilybe ixed at any point on the bar, so that the clamping ofthe cord m maybe .for a longer or'shorter period, `'and'thus the feed- 'rollers be in motion for a greater or lesser length of time, and the spinning be made 'coarse'r or ner, as may be desired. The lever t is shown'in blacklines in fig. 1 somewhat more elevated than it will be at anytime,

and it is thusl shown raised only temaket more distinct.

The cranklshaft ahas its bearings 6 on the standards A pulley br wheel, c', is-aiixed to the outer end of the crankshaft.- A. bander cord, d', passes around this pulley, and around the pulley e on the standard f', thence around thepulley g on theparriage Z, (see fig. 4,)-thcnce around the pulley h of -the roller z" to the pulleyc. From the pulley h a cord passes to and around the pulley j of the roller lc; `flhloughthis set of' pulleys thespindles and spools arerotuted; 'thelrst by cords irdm the-roller c, and the second cords from the roller z".` A pulley, l', (see fig. 1,) on the o therend of the roller t", has a cord passing aro-und it, and

around the pulley' m.of the rod or shaft n', by which this shaft is rotated. An arm; o passes lfrom the pulley m to a vibratinglever, 1J', which lever is attached to'the spool-bar. g. Thefends of the spool-bar pass through slots 1" and w inthe sides of the carriage. On' the opposite end of the rod or shaft n is a disk, s', with arm t', and which is connected with the vibrating-lever u', attached to the 'spool-bar q 'at that end, through alike slot, w', in the side ofthe carriage. The aruiso and t act as crank-arms, and'through the means here recited the spool-bar andspoolsare raisedand let down. 4 l l I The carriage Z-is .moved forward when -the b-evelled .wheel fc is in gea-r with-the clutch'y-, bevelled wheel then rotating thehorizontal bevelled' wheel Een the-'vertical Idrum a". A cord, f, is attached to the front end ofthe bar c", and passes around .the drum am, thence around the vertical pulley df to 4the back end of the bar cH. This bar, is notched or recessed at fl, 'and is held against the bottom bars g or frame yofthe ,carriage by suitable means. This notchj'lll allows some play of the bar at'the commencement of the action for the movement of the carriage, by which thstoot-h of the bar 7W', the lower end of which is inserted in -zt hole or slot in the bar 0', and its fulcrum,being'between this point and the tooth, is movedout from the recess of the roller 7c during the forward movement of' the-carriage, and into the recess of that roller during the back- 'ward movement of the carriage, so that the roller 'lf/ whichoperates the spindles is not in motion when the'car- Y* riage is on its return.

The carriagev is moved backwards when the bevelled wheel z' is .in gear with the clutch y', the changing of the clutch from the one; bevelled wheel to the other being produced 'at 'the end of the forward mo'vement of the carriage by the wheel c of the carriage-frame coming against, and operating Ythe lever Z, which, by ther-od m'", movesl the forkedhar 1W in one direction, and at the end of the backward movement oi' the carriage by the projecting barv 0 on the top of the carriage acting against the other arm of the forked bar, and moving it in the other direction. The forked bar 1W" Ais pivoted to the table -pmat g", (sec fig. 6.) The extension-piece 1" is notched, and embraces the end of' the lever 8", which moves the clutch y. A springbvar, 15', secured at the one end, u, passes across the lev`er's,.its end 11" turning down, as indicated at iig. 5. This spring-bar t is recessed at w", so that the movement=oi` the lever 8 is restricted at the return movemetof the carriagenntil this lever is liberated from the recess wmvby the elevating ot" the spring-bar t", which liberation isI produced by the pin x" elevating the end 11.` This elevation will' occur sooner or later, due tothe position of the pin in the wheel y'", which positionvmay be changed either'by putting the pin in a different 'part of wheel, or by changing the relative position of the wheel to the end of the spring-bar. The

Wheel y" isvon the inner end of a shaft, z, which has it bearings in an oscillating or rocking-box, a", the 'box beingeonnected to the bar bo'.; On the outer end of the shaft 2 is a toothed wheel, 0, to which isattaehed a weight, oZ,by a cord, e, the wheel 0 when-in' gear being moved or rotated by the screw-threads fo of a barrel orv collar, secured to the shaft a', pin, g, projects inwards from the inner end of Athe box ao. In the rotation of the-shaft a', while the carriage is travelling forwards and backwards, the screw-threads f" 't in the teeth of the wheelc", a spring, it", forcing the inner end of the box do downwards, and its outer end upwards, thus keeping the screw-threads andwheel in gear, and in this rotation the weight is wound up and the pin x" carried around and under the end' 11 of thc spring-bar il. The shaft roonti'nuing to rotate, the twisting of' the thread will continue.` The pin z elevates the end ofthe spring-bar', and liberates the lever 8', and allows the forked bar nHfree operation, so that the clutch istranst'erred from the wheelrzv to the wheel x for the advancing movement of the carriage, just previous to which the Wheel z' passes under thevprojectng pin g", tilting the box at', and ungearing the wheel 0 and screW-threadsf The twisting of the thread will therefore be more or lessdue to theperiod of timethat the shaft is rotating and the carriage at rest, which condition will be regulated by the earlier or later action of the pin 21 on the end v" ot' the spring-bar t".

What I claim asmyinven'tiom'and desire tov secure by Letters Patent, is

'1. The combination of the forks, levers t and r, plate v, and pin it, for clamping and liberating the cord, substantially as andfor 'the purpose herein recited.

2. Ivclaim the bar 7W', operated by the bar c", for holdin-g the roller c,vas and for the purpose herein described. l

3. I claim the wheel y", having the pin x, and the .other ineens' and devices connected therewith, substantially as described for the purpose herein recited. l
